Becoming 5 Kyu: Episode 6.

Hello everyone. Welcome to 'Becoming 5 Kyu'. I'm Shim Wooseop 7d.

Some people say "I've been 5 kyu for 20 years."

Others also say "I've been for 7 kyu for 30 years and only started improving recently."

Everyone shares the desire to improve their Go abilities.

I have a solution.

When we're sick, we need to go to see a doctor and get a prescription.

Similarly, we can view not improving for a long time as an illness.

This kind of Go player should see a better player.

And get a 'Go prescription'. Then, they should follow it.

The fastest way to improve is to correct bad moves and learn new Go skills.

Ok, let's move on to our lesson today.

Today is our last lesson about this opening.

We'll finish this opening completely.

I hope you've remembered everything we've learned about this opening.

But you shouldn't just try to remember it.

You should always try to use it in actual games.

We studied the opening from this move onwards.

We looked at variations of the 3-3 invasion.

This is a very basic and easy to remember joseki.

See how every move is carefully considered in terms of the whole board position?

Of course, there's no guarantee that white will invade here right away.

But if black jumps here now, which is a good followup,

It builds black's lower side.

This shape will almost always convert to territory.

White has many options now.

Whoever gets a chance will play in this area first.

Anyway, we've been looking at what happens when white invades here.

You've already learned about this attachment.

And also this attachment here. We also looked at this diagonal move.

Now we have only two more moves to consider. One is to cap here.

And the other is to make an iron pillar.

First, we are going to learn about this cap.

In this case, how should white play?

Black probably wants to tempt white to split here.

White may also want to play here even though it's what black wants.

Of course, it might not be bad at all to separate black.

But, black gets to keep sente.

Depending on the timing, black can play at the bottom.

Black can keep sente at the bottom and then take another big point.

So, now black needs to decide how to play at the bottom.

White has better moves here.

White shouldn't give black a chance to choose where to play next.

Even though it looks a bit strange, attaching here now is a good move.

This move also reinforces the corner.

Let's compare it with this. Now black can destroy the corner any time.

But this attachment removes such possibilities.

Now black must extend up.

If white doesn't want to give up her single invasion stone,

White can extend down.

Now white has miai. White can connect to the corner.

If black tries to stop the connection, white can extend along the other side.

Actually, there are some weaknesses in black's shape, so black can't attack too severely.

As a result, black gains little from this exchange.

It's better for black to block on this side, and white connects safely to the corner.

Then white can aim at black's weak points here later.

But note that white shouldn't play here right now.

Because these two stones have no value anymore, so black would build thickness.

If white wants to play around here, this two space jump is better.

White can capture on a larger scale later.

If black tries to save them, white would get more thickness on the left side.

Therefore, the cap leads to an unsatisfactory result for black.

In summary, when black caps, white just needs to remember 'attach and descend'.

So, we've mastered this cap.

What other options are there?

Most beginners would normally want to protect this side.

So this descent is often played. It looks like black has a nice position now.

But what will happen after this?

If white jumps, black would attach here or jump out along with white.

So, it's better for white to attach, to suppress the single black stone.

This black stone till has potential.

However, the timing of when to save it is important.

Living successfully in the opponent's camp doesn't always lead to a good result.

Saving stones is important, but playing on big points can't be ignored.

So I'll say it again - timing is important. Still, you need to know how to save this stone.

It's not a good idea to connect. Even though black saved the stone, white aim to cut.

So black has to play one more move here.

And white gets a large corner territory in sente.

Let's go back to here.

Taking the vital point of a tiger's mouth is usually effective.

Now white has two options; connect or close off the corner.

If white closes the corner, black can push through.

White has to block.

And black can capture the single white stone to the right.

White should just sacrifice once he's in this situation.

And the result? Black gets territory at the bottom.

White gets territory in the corner.

White also gets influence to use in the center, and sente.

Sente is paramount at this point.

Black did manage to save his stone.

But, consequently, white gets sente and takes a big point.

If black doesn't save this stone now, white will suppress it later.

But if white plays like this, there will still be some bad aji in the corner.

It's hard to deal with black's invasion at 3-3.

So normally white just reinforces the corner.

Now black can take a big point.

So it's not really urgent to save the black stone in this opening.

Black leaves some aji and plays somewhere, as you saw here.

If you want to play this probe, again, timing is crucial.

If white connects here, black must move toward the corner.

And when white hanes, black can also hane.

If white extends in the corner, black can connect along the side.

If white blocks from this side, black can easily live in the corner.

Even though white gets thickness, the corner is quite big.

So normally white blocks off the corner.

Going back here, this move is somewhat dispassionate, and it's also a bit passive.

Up to here, we've studied all the important variations in this opening.

Without this opening, we couldn't study all these moves.

And now that you've mastered them, you should practice this opening in your games.

Tempt your opponent to invade here in one of your games!

You'll be able to fight with confidence.

We've thoroughly investigated a basic opening.

Now let's move on to 'life and death'.

I've prepared a common position to start from.

In this position, splitting black is the best way to reduce his moyo.

When black approaches, white extends two spaces.

Black attaches here, to make white over-concentrated.

And then black encloses the corner with a knight's move.

We end up with a similar position to the one at the top.

At this point, we've already looked at the 3-3 invasion and its followups.

As you know, when white is weak here, the 3-3 invasion is not ideal.

Even though white can live, white's bottom group will be attacked severely.

And black can even think about to trying to capture it.

Until now, we've looked at this descent.

But white can still live in the corner with the knight's move or the push.

So this time, let's see what happens if black plays a tighter move.

This move is quite useful for weaker players to learn.

Now white can't play the knight's move.

Black can cut off the corner.

Well, what else can white do in this situation?

In this case, white can push here.

But this kosumi is better.

After this, white is almost alive here.

Black plays here.

White tries to make some eye shape.

Some players consider this atari but, in this case, it actually loses territory.

Black just needs to just block on the right side.

Then white should hane here to live.

Now white is alive.

Even if black ataris, white can just connect.

However, white is divided and black can attack white's bottom group.

Still, we've learned that white can live in the corner.

Let's examine some other possible moves in this situation.

When white plays here, it the same as in the lower right corner.

Can black play here to kill white?

If white plays as before, black can kill by descending.

But this empty triangle is a good move at this point.

Black has to block.

It looks like white doesn't have enough eye space in the corner.

However, this is a very famous life and death problem.

2-2 is often played in this kind of situation.

Now white has miai to live on either side.

If black descends here, white makes two eyes in the corner like this.

So in any case, black can't kill white in the corner.

Even though black made white live with less points,

Black also has a weak point, compared with the bottom right.

It's surely better to leave no weaknesses for the opponent to exploit.

Black can attack more severely after the variation at the bottom.

Now we know black can't kill white anyway. So black should play as in the lower right.

Ok, let's look at this in more detail.

Earlier I said black should block here without the atari.

But what if black blocks after the atari?

White will live by capturing one black stone.

Black can play like this in special cases.

When black attacks white, this descent is sente.

In that case, white would be in more danger.

Of course, white can choose not to respond because it's still a ko.

In terms of territory, black still made a loss here.

Let's compare this to the previous variation. White had only 4 points.

On the other hand, now white has 6 points.

It's only 2 point difference, but don't underestimate 2 points!

Small losses can accumulate into big losses.

Therefore black will avoid the atari where possible.

I've even seen players connect after the atari, but white's still alive.

If white just extends on the side, black would block and fight a capturing race.

But white can play strongly like this and it's easier.

Black can't kill white now.

If black hanes, white just connects. Cutting here and descending are miai.

I want to show you a famous life and death problem now.

Let's start with this position.

Many amateurs assume that white's dead here.

And I've even seen players resign now in actual games!

If white descends, black will wedge here.

White doesn't have enough eye space.

What about connecting? If black blocks here, white can live.

Here we have 'six stones in a row in the corner'.

According to Go proverbs, in the corner, four in a row die but six live.

But black could play the hane in the corner.

Now if white extends once more, but it's only six stones in a row.

On the second line, six in a row die but eight live.

So, how can white live here?

The answer is to play here. Now white's alive.

Even if black hanes in the corner, white can make another eye on the side.

If black blocks on the side, white can live by descending.

It's a rectangular four in the corner.

You can be sure that black has no way to kill white in the corner now.

Black needs to think about how to attack white severely after white lives.

Please don't just aim for the kill.

Consider the whole board position first.

This bring us to the end of lesson 6. Goodbye and see you next time.

Thank you!
